Detailed Description

ThreadContext is the external interface to all thread state for anything outside of the CPU.

It provides all accessor methods to state that might be needed by external objects, ranging from register values to things such as kernel stats. It is an abstract base class; the CPU can create its own ThreadContext by either deriving from it, or using the templated ProxyThreadContext.

The ThreadContext is slightly different than the ExecContext. The ThreadContext provides access to an individual thread's state; an ExecContext provides ISA access to the CPU (meaning it is implicitly multithreaded on SMT systems). Additionally the ThreadState is an abstract class that exactly defines the interface; the ExecContext is a more implicit interface that must be implemented so that the ISA can access whatever state it needs.

Member Enumeration Documentation

enum ThreadContext::Status
Enumerator
Active 

Running.

Instructions should be executed only when the context is in this state.

Suspended 

Temporarily inactive.

Entered while waiting for synchronization, etc.

Halted 

Permanently shut down.

Entered when target executes m5exit pseudo-instruction. When all contexts enter this state, the simulation will terminate.

virtual uint64_t ThreadContext::readIntRegFlat ( int  idx)
pure virtual

Flat register interfaces.

Some architectures have different registers visible in different modes. Such architectures "flatten" a register (see flattenIntIndex() and flattenFloatIndex()) to map it into the gem5 register file. This interface provides a flat interface to the underlying register file, which allows for example serialization code to access all registers.

Implemented in ProxyThreadContext< TC >, ProxyThreadContext< SimpleThread >, CheckerThreadContext< TC >, and O3ThreadContext< class >.
